The corpus spongiosum is a column of erectile tissue that composes the shaft of the penis. It extends through the urethra and is enlarged at the end to form a sensitive, cone-shaped glans penis, which covers the ends of the corpora cavernosa and bears the urethral opening. Inside the glans penis, the corpus spongiosum is dilated and forms the navicular fossa.
